RAIN-WATER CUT-OFF.

' SPECIFICATION forming part of Letters Patent No. 498,663, dated May 30, 1893. Application filed February TO, 1891 Serial No. 330,898. (No model.) l i To all whom it may concern: 1 g

. Be it known that I, MATHIAsA. LA SKA, of the city of New Orleans, in the parishofOrleans and State of Louisiana, have invented anew andlmproved Rain-Water Out Offl'of which the following is a-full, clear, andexact description.

My invention relates to improvements in that class of devices whichare adapted to automatically controlthe flow of rain water 7 into a cistern, and, the object of my invention is toproduce a simple, durable and-easily regulated device, which will operate'in such claimed.

a manner that the water with the dust and 'dirt which is Washed 01? from thereof of a buildingatthe beginning of a rain, will be directed awayfrom' the cistern, and which, when the water has become clean, will direct the flow into the cistern. t To this end my invention consists in certain features of construction and combinations of parts, which will be hereinafter described and Reference is tobe had to the accompanying drawings forming-a part of this specification, in which similar letters of reference indicate corresponding partsin both the figures.

Figure 1 is a side elevation partly in section, of the entire device, as appliedto acistally, it having on the under side a depend tern; and Fig.2 is a broken plan view of the same.

The main elbow A connects'with the ordinary rain water conductor in the usual way, and is adapted to deliver into the" cistern B. The elbow is held, however, to swing horizoning roda which is mounted in thelugs c of a plate 0, which plate is secured to the cistern but may be secured to any convenient support. The movement of the elbow A is limited by a keeper 0/ which is secured to the under side of the elbow, and the ends of which are bent downward so as to embrace the edge" of the cistern, and these depending ends pre-' vent the elbow frommoving too farin either Near the main vertical portion of oted a rodF, the opposite end of the rod being pivoted to the vertical arm G of the three armed lever .6, so that when the lever is tilted,

. The sand box is provided made to turn.

the rodF will be moved, and the elbow A t The lever G is centrally pivoted on a sup- 7 port H, secured to the cistern, and from one I V horizontal arm thereof is suspended aweight J which is heavy enough to normally swing the elbow A-, so that it will not deliver into I the cistern, and to thelopposite arm of thele- Q .ver is booked the bail k of the sand box The lever is notched onthe lowerside, as

shownatg, and thereat restsupon astud h on the support H, the stud serving as aguide l l for the-lever and also serving to. relieve its central pivot of a portion oftheweight of the lever and 'itsattachments.

a chamber k which has 'an opening it in one side. Thepartition k hasacentralconical opening therein, and extending upward through and engaging the bottom of the tube,

is a screw L having a conical point which fits and'enters the opening inthe partition} of water throughthe' valved opening. More v over since the box is wholly separate from and exterior to the pipe leading to'the cistern none if the water in its course to the cistern" had to pass into the box or vessel K and overflow 1. j I

into the cistern pip with sand M, there The sand box K has a depending ,tube K f opening from the bottom, which tube'is closed 2i I V at its lower end and is provided near thebot tom with a transverse-partition is, thus form- .7 l I .75 'Y The sand packs snugly in the box or vessel K and by partly 'absorbing andpartly checking the water causes the latter to drop'evenly" y from the beginninglto the endof 'the opera-] 8o v of the foreign matter collectingtherein can be washed into the cistern as would be thecase I being suflicient to till the tube and to par tially, fill the box,the sand beingjheld in place I by acover O which rests loosely upon-it, and

which is providedfon the stop with a handle 0, by means of 'whichit may be removed. A large funnel P is secured to thecistern, and the lower end of the funnel terminates in a pipe P which is made to deliver into the sand box. As shown in'the drawings, the fun- Ico Q ncl P is supported on the cistern,but as the funnel must be out of doors where it will be exposed to the rain, it the cistern should be located in doors, the funnel maybe secured to any other convenient support.

The operation of the device isas follows:

. The weight J is heavy enough to more than Weight J, and thus tilt the lever and swing the elbow A so that the water from the root will be delivered into the cistern. The screw Lin the sand box is adjusted so that water therein will drop out very slowly, and coni sequen'tly after the elbow has been thrown to" connect with the cistern, it will bererain' again within a very short time, the water w'ould"b'e delivered iuto the cistern at once but' if a considerable time intervenes between the rains, the water willfi'rs't ruuto Waste, as described, as the waterwill' have drippedthrough the'opening's in the bottom of thesand box. The le'n'gth of time'during whichthe' wate'r runs to waste may be gove'irnedby adjusting the weight J, and the sand boxiu relation to each other.

lt willb'e noticed that the cover 0 in the sand box hasla flange around the upper edge, so'that the dust which runs into the sand box from the funnel, will be caught upon the cover so that it maybe conveniently emptied. v

I-Ia'vin g thus f ully described m y invention,

I claim as new and desire to secure by Letters Patent- 1. The combination with the swinging pipe delivering to the cistern and receiving Water from the rain spout, of a counterbalanced lever normally holding the swinging pipe out of connection with the cistern and provided with a suspended ,open water-receiving vessel exterior to and independent ofthe pipe leading to the cistern and a permanently open pipe for conducting Water to the saidvessel to cause it to operate the said lever and connect the swinging pipewi'th -the cistern, substantially as set forth. v

2.- The combination with the swinging pipe to connect the rain spout and cistern and pro vided-with a counterbalanced levernormally disconnecting it from the cistern,- of a vessel suspended from thesa'id-lever exterior to and ind-ep'ehdentof the cistern pipesa regulating valvein thebot-tom of the vesse-l,*anexposed funnel or gatherer into which ,the'ra'in may fall-and having a pipe leading to the said vessel, substantially as set forth; 7 tained in that position for a considerable length of time, so that after a rain, it"it'should 3. The combination With'acistern having an opening'in itsupper end, of a horizontally swinging elbow pipe mounted on said cistern to registerwith saidopen'in'g; a counterbalanced lever mounted on theci ster'n and con nected with said elbow pipe to normally dis1 connect it fromthe cister'n a vesselsuspended from the lever andwhollyiude'pendent of the elbow pipe andcistermand having a valved drip opening in its bottom, an exposed rain gathering funnel above the vessel and having a pipe leading'thereto; said vessel being adapted to contain a body of sand above its valve, substantially as set forth. v
